I agree it looks strange in the Choice Adventure chooser, at the moment I'd only looked at decorating the relay browser. I can't currently explain why you'd always use the key whichever you pick, though.
My thoughts for automation options, will this meet people's requirements?
I wanna be a door:
Show in browser
Unlock door if possible, otherwise show in browser (Will use in order pick-o-matic, PYEC, skeleton key) [question, should I allow last skeleton key to be used? ]
Unlock door if possible, otherwise mainstat test
Mainstat test
It's Almost certainly a trap:
Show in Browser
Elemental Test
Use pole if you have it, otherwise show in browser
Use pole if you have it, otherwise Elemental Test
The First Chest isn't the deepest and Second Chest
Show in Browser
Get item
Skip through door if wearing ring, otherwise skip chest
Skip chest
Thoughts, before I implement ?
